Real-world test on a 321-file TS/Svelte monorepo flagged 454 magic-number findings, ~82% of them noise: literals already assigned to a named const/field and numbers merely buried under a binary expression (e.g. a call arg inside a string concat). Tighten all 5 languages to: (1) require the literal be a DIRECT operand of a binary/comparison expression, and (2) exclude initializers of a named binding (const/var/let/field). Cuts magic-number ~67% with no loss on fixtures (each language still detects its genuine `x > 5000` case). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
